The throttle valve 17 has an independent connection With the boiler, and is actuated through the foot pedal 25, wherebyvprompt acceleration and variable speed is attained, thereby especially adapting the vehicle to city traflic.

The steam turbine 18, consists of a casing 26, provided at the top with inlet ports 27, 28, and atthe bottom with an exhaust port 29. The rotor 30 is fixed to the shaft 31, journaled in spherical bearings 32, to secure alinement of bearings and shaft. The rotor 30 is provided on its periphery with U-shaped diagonally disposed impact blades forming a series of passages for the steam. The steam enters the passages on one side of the periphery of the rotor, through the corresponding inlet ports, and, as may be understood from the disclosure in Fig. 6, emerges on the opposite side of the periphery, and discharges into the supplementary port 33, and is again directed to impinge upon the rotor on the side of the periphery as first described. The turbine is reversed in direction of rotation by admitting steam through the opposite inlet port. The steam admitted through either port, is twice used to deliver impulses to the rotor, thereby securing economy in the generation of power. The bearings are lubricated by rings 34 running in oil pockets 35.

The throttle valve shown in Fig. 3, consists of the valve -casing 36, havin therein the pressure chamber 37, into w ich a valve member 38, of bevel disk form, opens. The

valve is actuated by the plunger 39,'on which is mounted the foot pedal 25; a spri'ng 40, normally holding the valve in closed position.

The valve shown in Figs. 7, 8, is employed to control the admission of steam to the motor and to the brakes. The casing is provided with the port 9 through which steam may be admitted to! diagonally opposite f rakes 4, 7, and with a port 12 to admit steam pressure to the brakes 5, 6. Exhaust port 41 is provided to release the pressure upon the brakes when the valve is shifted to release position. Steam is admitted to `"the valve through the opening 42, in direct communication with the boiler. Port 43 is provided to control the admission of steam to the motor, having communication through a manifold 44, with the forward inlet port 27, of the motor. Reverse port 45, of the valve, is similarly in communication with reverse port 28, of the motor. The inner rotating valve member 46, is providedn with tubular passages 47, 48, 49, 50, having no communication with the interior of the valve. The port 51 is adapted to register with either port 43, or port 45, to supply steam pressure to the motor. The valve, when set as shown in Fig. 8, supplies steam pressure to impart a forward motion to the vehicle. In this position the passages 48, 49, are, respectively, in communication with brake ports 9, 12, and the passage 52 registers with exhaust port 41, thereby releasing the brakes. In the brake position shown in Fig. 7, the ports 53, 54, are respectively, in communicatlon with brake ports 9, 12, thereby applying the brakes to the vehicle. To drivevthe vehicle in reverse position, the port 51 is placed in communication with port 45. In this position of the valve, passages 47, 48, register with brake ports 9, 12, and port 50, with exhaust port 41, to release the brakes.

From the foregoing it may be seen that I have produced a simple and efficient power plant for the propulsion of motor vehicles. The boiler is placed under the hood, and as far away from the passengers as possible. The boiler is close to the turbine motor' with a simple control valve and manifold interposed, so that but little steam is lost through evaporation. The turbine can be readily reversed by a lsingle movement of the valve controlled 'by the fingers of the driver. Practically no oil gets into the steam and it can be condensed and used over and over again without being separated. The turbine takes up -but little room, and requires almost 95 no attention. The turbine is geared `to the drive shaft in the ratio of say, 4 to 1; the transmission. gear box 551, being directly v at the rear of the turbine. No clutches are necessary. Gears are always in mesh, and 100 any ratio of gears may be employed to secure the desired flexibility, ease of acceleration, and other qualities desired.

The turbine motor is mounted on crossbars 5,6, of the vehicle frame. While the 105 specification is more or less specific as to certain of the parts, the invention resides in the combination of parts, their simplicity, and their adaptability to accomplish the objects of the invention.

What is claimed is:

1.
